This weekend was my sisters 35th birthday, and so off we went for a Sunday roast lunch at Fallow.

The Sunday roast at Fallow is a fantastic meal for a celebration, with enough new things to be special, and the classic comfort of a roast to be intimate.

From the moment you walk in, it’s clear this isn’t a quiet corner of Mayfair – instead, diners are loud and animated, and fill the room to the brim. As a result, the whole experience feels energetic and intentional, which suits a London Sunday lunch perfectly.

We arrived focused on one thing: a proper London roast. That single goal shaped every choice we made.

First impressions of a Sunday roast at Fallow

To begin with, Fallow on a Sunday is full. Not gently busy, but properly packed to the rafters. Tables are close together, with as many people at high tables and the bar as there are around more traditional dinner tables. The dining room stays loud from start to finish.

Consequently, this is not the place for an intimate celebration or a deep, meaningful conversation. However, for a relaxed lunch with close friends where food takes centre stage, it works well.

Even so, the service holds together impressively. Despite the pace, staff stay attentive and calm. Drinks arrive quickly and plates clear on time. Nothing feels forgotten. That sense of control keeps everything running smoothly, especially when the restaurant runs at full tilt.

Breaking bread

We started, as many do, with softdough and whipped butter. While this sounds basic, it immediately sets expectations. The bread arrived warm, with a crackly crust and a soft, bubbled centre. Meanwhile, the butter melted almost on contact. Together, they worked exactly as intended. Simple, but well executed.

Shortly after, the corn ribs appeared. At this point, the table shifted from polite sharing to focused eating. The ribs smelled smoky and tasted even better. Sweetness, savoury notes, and a gentle char all came through. As usual, they proved dangerously more-ish, and stopping at one felt impossible.

If anything, these are the kind of dishes that remind you why people return to Fallow.

The venison haunch

Next came the venison haunch, arriving juicy and tender, with no hint of dryness. More importantly, the flavour stayed rich without tipping into anything overpowering.

Alongside it, a tangy sauce cut through the meat beautifully. We also ordered kombu fries, which added depth and a subtle savoury edge. Each element played a role, and nothing felt excessive. Because of that balance, we kept reaching back for another bite.

Sunday roast lunch at Fallow

Naturally, the focus of a Sunday roast lunch at Fallow is the roast itself. Two sirloin roast lunches arrived, and they looked reassuringly generous.

First, the beef. It came pink, juicy, and clearly rested. Each slice stayed tender, which is not always a given on a busy Sunday. Just as importantly, the gravy delivered real depth. It tasted rich and beefy, and it encouraged liberal pouring.

The Yorkshire puddings followed suit. Crisp on the outside and soft within, they held their shape and soaked up gravy well. Meanwhile, the roast potatoes stole the spotlight. Crisp edges gave way to fluffy centres, and the generous coating of gravy only made them better.

With all the meaty, potatoey, gravy goodness, who can blame us for neglecting the two cabbage sides?

In a city obsessed with roasts, this one easily holds its ground. It feels generous, satisfying, and well judged. As a result, it earns its place among conversations about the best Sunday roast in London.

Dessert decisions

Dessert, however, split opinion.

First up was the cookie dough soft serve with truffle. On paper, it sounded playful and indulgent. In reality, it failed to justify its £15 price tag. Firstly it was a pretty meagre portion, and the cookie ‘dough’ felt more like crispy cookies.

I don’t know – this one just fell flat. Although the truffle addition felt different (and sort of interesting), it never felt truly enjoyable. Consequently, we lost interest quickly and would not order it again.

Thankfully, the Chelsea tart with whey and milk ice cream turned things around. The tart was rich and comforting, while the ice cream added balance rather than heaviness. Together, they worked beautifully.

Ending on a strong note matters, and this dessert delivered.

Overall thoughts of Sunday roast lunch at Fallow

Overall, the Sunday roast lunch at Fallow feels bold, busy, and focused on flavour. It is not trying to recreate a traditional pub roast. Instead, it offers a modern take that prioritises quality ingredients and confident cooking.

Because the restaurant stays loud and full, it suits a lively London Sunday lunch better than a quiet occasion. Nevertheless, when the roast is this good, that trade off is fine.

Between excellent beef, standout potatoes, strong starters, and one very good dessert, Fallow proves it belongs in the wider discussion about the best Sunday roast in London. It may not be perfect, but it is memorable. And it’s a great location to celebrate a 35th birthday!
